  2. Zinc oxide nanostructure - Wikipedia

    en.wikipedia.org/wiki/Zinc_oxide_nanostructure

    ZnO creates one of the most diverse range of nanostructures, and there is a great amount of research on different synthesis routes of various ZnO nanostructures. [1] The most common methods to synthesise ZnO structures is using chemical vapor deposition (CVD), which is best used to form nanowires and comb or tree-like structures.

    ZnO is a wide-bandgap semiconductor with an energy gap of 3.37 eV at room temperature. [1] ZnO nanoparticles are believed to be one of the three most produced nanomaterials, along with titanium dioxide nanoparticles and silicon dioxide nanoparticles. [2] [3] [4] The most common use of ZnO nanoparticles is in sunscreen.

    The diameter of the nanowire which is grown depends upon the properties of the alloy droplet. The growth of nano-sized wires requires nano-size droplets to be prepared on the substrate. In an equilibrium situation this is not possible as the minimum radius of a metal droplet is given by [ 4 ]

  5. Nanorod - Wikipedia

    en.wikipedia.org/wiki/Nanorod

    Zinc oxide (ZnO) nanorod, also known as nanowire, has a direct bandgap energy of 3.37 eV, which is similar to that of GaN, and it has an excitation binding energy of 60 meV. The optical bandgap of ZnO nanorod can be tuned by changing the morphology , composition, size etc.

  6. Nanowire - Wikipedia

    Most synthesis techniques use a bottom-up approach. Initial synthesis via either method may often be followed by a nanowire thermal treatment step, often involving a form of self-limiting oxidation, to fine tune the size and aspect ratio of the structures. [7] After the bottom-up synthesis, nanowires can be integrated using pick-and-place ...

    The ZnO nanowire templates are then removed by thermal reduction and evaporation. An analysis using transmission electron microscopy (TEM) shows that ZnO residue, along with a thin film of porous GaN, is still found in the upper portion of the nanotubes after the templates are removed. This is a result of zinc and oxygen coming off of the ...

  8. Nanoring - Wikipedia

    en.wikipedia.org/wiki/Nanoring

    A nanoring consisting of 40 porphyrin subunits. [1]A nanoring is a cyclic nanostructure with a thickness small enough to be on the nanoscale (10 −9 meters). Note that this definition allows the diameter of the ring to be larger than the nanoscale.

  9. Nanosensor - Wikipedia

    [4]: 12–26 Zinc oxide nanowire is used for gas sensing applications, given that it exhibits high sensitivity toward low concentration of gas under ambient conditions and can be fabricated easily with low cost. [9]
